Abstract

Conventional methods for diagnosis of human disease are, at times, limited in different regards including time requirement, either experimental or data processing, sensitivity, and selectivity. It is then that a Point of Care Criteria, which considers the true utility and usefulness of the device, is employed to propose new diagnostic devices capable of overcoming the aforementioned shortcomings of conventional tools. Nucleic acid, characterized for its predictable base-pairing nature, is considered to be a highly-selective, yet greatly modifiable device. Its behavior is then described through Boolean Logic, where “true” or “false” outputs are mathematically described as “1” and “0”, respectively. This mathematical approach is then referred to as Logic Gates, where outputs can be predicted based on satisfied environmental conditions. The mechanisms, capable of exhibiting Logic Gate behavior, are described.
